I had the same choice on my lap. An aging 5Dc and either the 5D2 or 5D3?

I was never impressed enough with the 5D2 as an overall camera but the d700 felt like a complete package. The d700 had everything except video and resolution from my 5Dc and that it can't take EF lenses.

So I skipped the mk2 cameras entirely and went straight into a mk3. It's all the camera I could ever need and won't be outgrowing it any time soon.

I'm with you Rev. Decided to skip the 5d2 and the 7d2 and went straight to the 5D MK III. Very happy I did! Now, I still have my 7D, but unless it's a wicked crazy upgrade, 7D2 probably won't happen for me... I'm liking the 5D III!
